Activity Overview
In this activity, students graph the cubic and quadratic functions. They also graph the slope values of the tangent lines for each of the function graphs.
Before the Activity
Install the CellSheet on the calculator using the TI Connect™, TI-Connectivity cable, and Unit to Unit cables
See the attached PDF file for detailed instructions for this activity
Print pages 67 - 72 from the attached PDF file for your class
During the Activity
Distribute the pages to your class.
Follow the Activity procedures:
Use the quadratic equation and for different x-values find the corresponding y- values
Determine the slope of the secant line that passes through 2 points
Determine the Δx - slope relationship
For values of x, use the cubic equation to find the corresponding y-values
Determine the slope of the secant line and Δx - slope relationship
Compare the Δx - slope pattern for the cubic quadratic function curves
After the Activity
Students will complete the worksheet and answer questions.
Review student results:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
